So a common way for feminists to respond to stats showing discrimination/violence towards men is that it's "other men doing it to men".

Okay and? Why does your "empathy" end when it's being done by someone of the same group? If you had any shred of empathy, you'd know we're meant to care about the victim, not the perpetrator. What if we were to apply this logic to other groups?
Black people who die to gun violence don't matter because it was done to them by other black people.

Lesbians who are in abusive relationships don't matter because their abuser is also a lesbian.

Who cares if a little girl got bullied and called a whore? It was done by other girls so it is not an issue.

Wow, the world seems a lot nicer when you just victim-blame the victims because they share an arbitrary trait with the person victimizing them. Why do people not care about male-on-male rape/violence just because the perpetrator is a male? Sure, there's never been a female organization who's kidnapped a 100 little boys, but there is the 10,000 young boys Boko Haram took. Do they not matter just because it was men who took them? Do these little kids deserve to be harmed because they are boys? Do the male soldiers of war not matter because they were shot down by other male soldiers?
What is your guy's thoughts on this argument?
